UTP3305 3Ch 335W 32V/5A Linear DC Power Supply
Product Details
UPC: 6935750533079
Manufacturer: UNI-T
Warranty: 3 years
Literature: https://instruments.uni-trend.com/download?cate=43
Equipment Type: DC Power Supply
The UTP3305 is a three-channel linear bench DC power supply with 335 W total output. CH1 and CH2 are adjustable from 0–32 V at 0–5 A, and CH3 provides a fixed 5 V at 3 A for logic-level power. Linear regulation holds output ripple under 1 mVrms.
An automatic CV/CC crossover with current-limit protection transitions between constant-voltage and constant-current operation as the load changes. CH1 and CH2 combine in series for up to 64 V or in parallel for up to 10 A from the front panel, with a master-slave tracking mode for matched dual-rail testing. Independent voltage and current readouts are shown per channel, with a front-panel master output ON/OFF.
Operation is knob-and-button from the front panel with no remote interface, suiting it to higher-current bench work, low-noise analog tasks, and education.
